Mode of Disclosure

As the disclosure allows for various changes and numerous embodiments, embodiments will be illustrated in the drawings and described in detail in the written description. However, this is not intended to limit the disclosure to particular modes of practice, and it is to be appreciated that various modifications, equivalents, and/or alternatives that do not depart from the spirit and technical scope of the disclosure are encompassed in the disclosure. In the description of the disclosure, certain detailed explanations of the related art are omitted when it is deemed that they may unnecessarily obscure the essence of the disclosure.

In the specification, it is to be understood that the terms such as “including,” “having,” and “comprising” are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof disclosed in the specification, and are not intended to preclude the possibility that one or more other features, numbers, steps, actions, components, parts, or combinations thereof may exist or may be added.

In the specification, the expressions such as “A or B,” “at least one of A and/or B,” or “at least one or more of A and/or B” may include all available combinations of items listed together. For example, the expressions such as “A or B,” “at least one of A and B,” or “at least one of A or B” may signify all cases of (1) including at least one A, (2) including at least one B, or (3) including both of at least one A and at least one B.

Terms such as “first” and “second” are used herein merely to describe a variety of constituent elements regardless of an order and/or importance and to distinguish one constituent element from another constituent element, but the constituent elements are not limited by the terms. For example, a first user device and a second user devise may denote different user devices regardless of an order and/or importance.

FIGS. 1A and 1B illustrate a state in which a plurality of characters are identified and displayed according to a user's selection on an electronic apparatus according to an embodiment.

According to an embodiment, an electronic apparatus 10 may display various contents on a display 11. For example, the electronic apparatus 10 may display contents such as image, video, text, or the like, on the display 11. The display 11 may include a touch screen display. The electronic apparatus 10, in response to a user input to select various contents displayed on the display 11, may provide new information related to the selected content, or identify a part of the selected content and provide a user with the identified part separately from the other part of the content.

Referring to identification number 1-a of FIG. 1A, the electronic apparatus 10 may display characters on the display 11.

For example, the electronic apparatus 10 may display characters on the display 11 by executing a document file stored in the electronic apparatus 10, for example, word document files, portable document format (PDF) files, or the like. For example, an operating system (OS) running on the electronic apparatus 10 may control a word file execution application that may execute a word document file to execute a word document file selected by a user to be displayed on the display 11.

Alternatively, the electronic apparatus 10 may display characters on the display 11 by accessing a web server to download online magazines, online newspapers, or the like. For example, the OS running on the electronic apparatus 10 may download online magazines, online newspapers, or the like, in the form of a file format, from a web server. The OS may control an execution application capable of executing a downloaded file to execute a document file to be displayed on the display 11.

Alternatively, as a web server accesses the electronic apparatus 10 to control the display 11 of the electronic apparatus 10, online magazines, online newspapers, or the like on the web server may be displayed.

Referring to identification number 1-b of FIG. 1 a , the electronic apparatus 10 may receive a user input 105 to select at least one of the characters displayed on the display 11.

According to an embodiment, a user may select at least one character to conduct an additional search for a specific word, a specific phrase, a specific clause, or a specific sentence included in an article displayed on the display 11. The example, the electronic apparatus 10 may receive a user touch input 105 to select a character, that is, an

112, from a word, that is, a

110, displayed on the display 11. According to an embodiment, the user touch input 105 may be a long touch input of touching the

112 for a preset time or more, or a multiple touch input of touching the

112 a plurality of times within a set time. However, the user touch input 105 is not limited thereto.

According to various embodiments, the electronic apparatus 10 may receive an input of selecting the

112 from the word, that is, the

110, as a user manipulates physical keys included in the electronic apparatus 10.

According to an embodiment, the electronic apparatus 10, in response to a user input to select at least one of the characters displayed on the display 11, may analyze a sentence including at least one character by using the sentence and the at least one character, and select a character set included in the sentence according to an analysis result.

For example, the electronic apparatus 10 may obtain a plurality of character set candidates including the character selected corresponding to the user input and at least one of the neighboring characters, obtain a plurality of candidate sentences respectively corresponding to a plurality of character set candidates, analyze the obtained candidate sentences, select one candidate sentence, and select a character set corresponding to the selected one candidate sentence.

In detail, the electronic apparatus 10, in response to a user selection, may obtain a character set including the selected character and at least one of the neighboring characters. Obtaining a character set may mean, for example, determining one character set including a selected character and characters present within a preset distance from the selected character. The electronic apparatus 10 may obtain a plurality of character set candidates by repeatedly performing the operation of obtaining a character set.

For example, the electronic apparatus 10 may determine

, and the like, including the

112 that is the character selected by a user, to be character set candidates.

According to an embodiment, the electronic apparatus 10 may obtain a plurality of candidate sentences respectively corresponding to a plurality of character set candidates, analyze the obtained candidate sentences, select one candidate sentence, and select a character set corresponding to the selected one candidate sentence.

For example, the electronic apparatus 10 may obtain the connectivity score of the character set candidates by analyzing the obtained candidate sentences.

Analyzing a sentence may mean, for example, that the electronic apparatus 10 analyzes a correlation between characters or words forming a sentence. Alternatively, analyzing a sentence may mean, for example, an operation of identifying whether relations between characters or words forming a sentence are continuous or non-continuous. Alternatively, analyzing a sentence may mean, for example, analyzing grammatical relations between characters or words forming a sentence. Alternatively, analyzing a sentence may mean, for example, analyzing grammatical roles of characters or words forming a sentence. Alternatively, analyzing a sentence may mean performing the above-described analysis processes sequentially or simultaneously.

According to an embodiment, the connectivity score may be a score given to a character set as a result of analysis of the above-described sentence. For example, the connectivity score may be a score given to a character set as the electronic apparatus 10 calculates a degree of connectivity in relations between the character set and other characters in a candidate sentence.

For example, the electronic apparatus 10 may obtain

that is a candidate sentence including the

112 that is the character selected by a user. The operation of obtaining a candidate sentence including the character selected by a user may mean, for example, determining a candidate sentence by using an artificial intelligence (AI) model trained to distinguish a boundary between sentences by using closing words for terminating a sentence.

The electronic apparatus 10 may obtain a plurality of characters including the

112 in a range of the obtained candidate sentence, as one character set. For example, the electronic apparatus 10 may determine

,

, or the like, including the

112 that is the character selected by a user, to be one character set. However, the disclosure is not limited thereto. For example, the electronic apparatus 10 may obtain a plurality of characters including the

112 beyond the range of the obtained candidate sentence, to be one character set. In this case, the electronic apparatus 10 may exclude a character set that does not form a word, from the obtained character sets.

For example, as in identification number 1-c of FIG. 1B, the electronic apparatus 10 may obtain

as a first character set candidate. Furthermore, the electronic apparatus 10 may obtain

as a second character set candidate and

as a third character set candidate.

According to various embodiments, the electronic apparatus 10 may obtain, for example, the first character set candidate, the second character set candidate, and the third character set candidate, and combine the obtained character set candidates with another character in a sentence to generate a new character set candidate.

According to an embodiment, the electronic apparatus 10 may obtain a connectivity score with respect to a plurality of character set candidates on the basis of the analysis of a candidate sentence including the obtained character set. For example, when the obtained character set candidate is substituted with other words, the electronic apparatus 10 may distinguish whether the substituted word has independency or dependency in relation with other words or characters included in the sentence.

According to an embodiment, the electronic apparatus 10 may select one character set from among a plurality of character set candidates according to the connectivity score. The one character set selected by the electronic apparatus 10 may be, for example, a character set having a high connectivity score according to a result of the analysis of a sentence. A character set having a high connectivity score may be, for example, a character set that is highly likely to be selected by a user.

In detail, the electronic apparatus 10 may apply a work

to a sentence instead of the first character set candidate, the second character set candidate, and the third character set candidate.

For example, as the connectivity score is closer to 1, it may mean that a candidate character set is highly likely to be used by being connected to other characters included in a candidate sentence. Furthermore, as the connectivity score is closer to 0, it may mean that a candidate character set is highly unlikely to be used by being connected to other characters included in a candidate sentence.

For example, the electronic apparatus 10 may apply the word

instead of the first character set candidate, to the candidate sentence, and obtain a candidate sentence

The electronic apparatus 10 may apply the word

, instead of the second character set candidate and the third character set candidate, to the candidate sentence, and obtain candidate sentences

.” and

The electronic apparatus 10 may identify

to be a non-existent character set, though it is not grammatically incorrect in the candidate sentence, and give a connectivity score of 0.72.

The electronic apparatus 10 may identify

to be a character set that is not much used, in which a postposition word is grammatically omitted in the candidate sentence, and give a connectivity score of 0.65.

The electronic apparatus 10 may identify

to be a character set that is combinable and has no grammatical error in the candidate sentence, and give a connectivity score of 0.78.

The electronic apparatus 10, on the basis of an identification result, may identify that

that is the first character set candidate has the largest connectivity score. In other words, the connectivity score may mean a degree of fluency in terms of grammar or meaning of a substituted character set in connection with other character sets of a candidate sentence when one character set is substituted by another character set in the candidate sentence.

According to various embodiments, the electronic apparatus 10 analyzing a candidate sentence to obtain a connectivity score may be one of embodiments of the disclosure. For example, the electronic apparatus 10 may analyze a phrase to which a character set belongs, a clause to which a character set belongs, a paragraph to which a character set belongs, or a piece of document to which a character set belongs. In other words, the electronic apparatus 10 may analyze a plurality of characters forming a sentence, a phrase, a clause, a paragraph, or a document, and select one character set included in the characters.

Referring to identification number 1-d of FIG. 1B, the electronic apparatus 10 may display a selected area notification object on the display 11 to display the identified one character set to be distinguished from other characters.

For example, the electronic apparatus 10 may display an area 120 adjacent to a character set including the identified characters

by changing the color of the area 120. However, the disclosure is not limited thereto. For example, the electronic apparatus 10 may display the characters

in a color different from the color of other characters, or by changing the thickness of the characters.

According to various embodiments, while the area 120 adjacent to

is displayed by changing the color thereof, the electronic apparatus 10 may receive a user input to select another character displayed on the display 11, for example,

of

. In this case, the electronic apparatus 10 terminates displaying the area 120 adjacent to

by changing the color thereof, and sequentially, display an area adjacent to

by changing the color thereof.

As such, according to an embodiment of the disclosure, when a user tries to conduct an additional search or the like by selecting a word display on the display 11, inconvenience of adjusting a start point and an end point of each of a word, a phrase, and a clause to select a desired word, phrase, or clause may be reduced. For example, as described above, when a user selects one character only, a character set including the selected character and being highly likely to be selected by a user considering the meaning and/or structure of a sentence including the selected character is identified and displayed to be distinguished from other characters.

FIG. 2 is a schematic block diagram of an electronic apparatus according to an embodiment.

Referring to FIG. 2 , the electronic apparatus 10 may include a processor 210, a display 220, and a memory 230. The electronic apparatus 10 may further include a communication module 240. However, the disclosure is not limited thereto. The electronic apparatus 10 may include more constituent elements or exclude some constituent elements to perform the function of the electronic apparatus 10.

According to an embodiment, the processor 210 may control the overall operation of the electronic apparatus 10. For example, the processor 210 may execute a stored program by controlling the memory 230, or retrieve or store necessary information.

According to an embodiment, the processor 210 may control the display 220 to display at least one sentence, receive a user input regarding at least one character of the displayed sentence, analyze the sentence by using the sentence including at least one character and the at least one character, in response to a user input, select a character set included in the sentence according to an analysis result, and display the selected character set to be distinguished from other characters included in the sentence.

According to various embodiments, the electronic apparatus 10 may include a plurality of processors. For example, the electronic apparatus 10 may include a general-purpose processor and an AI dedicated processor.

The AI dedicated processor may be, for example, a processor that is more integrated, has less delay, has better performance, or more resources than a general-purpose processor.

According to an embodiment, the AI processor may quickly and efficiently process a large amount of calculation needed for generation, updating, or application of an AI model, compared with the general-purpose processor.

According to an embodiment, the general-purpose processor may control the display 220 to display at least one sentence, receive a user input to select at least one character of the displayed sentence, and select a sentence including the selected character.

The AI processor may receive a selected character and a sentence including the selected character from a general-purpose processor, analyze a sentence by using the selected character and a sentence including the selected character, select a character set included in the sentence according to an analysis result, and transmit the selected character set to the general-purpose processor. For example, the AI processor may obtain a plurality of candidate character sets including a selected character, produce a connectivity score with respect to the candidate character sets, and select one character set.

The general-purpose processor may display a received character set to be distinguished from other characters.

However, the operation performed by each processor is not limited thereto. For example, the electronic apparatus 10 may allow each processor to separately perform operations in various forms.

According to an embodiment, the display 220 may display an image, a video, text, and/or an execution screen of an application. When the display 220 is implemented by a touch screen display, the display 220 may be used as an input device in addition to an output device. The display 220 may include at least one of a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a 3D display, an electrophoretic display, and the like.

According to an embodiment, the display 220 may display at least one sentence and receive a user input to select at least one character included in the displayed sentence, under the control of the processor 210. Furthermore, the display 220 may, under the control of the processor 210, display a set of the identified characters to be distinguished from other characters.

According to an embodiment, the memory 230 may include at least one type of storage media such as a flash memory, a hard disk, a multimedia card micro, a card type memory, for example, SD or XD memory, random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), programmable ROM (PROM), a magnetic memory, a magnetic disc, an optical disc, and the like.

According to an embodiment, the memory 230 may store instructions which are configured such that the processor 210 controls the display 220 to display at least one sentence, receive a user input regarding at least one character of the displayed sentence, analyze, in response to a user input, a sentence by using at least one character and a sentence including the at least one character, select a character set included in the sentence according to an analysis result, and display the selected character set to be distinguished from other characters included in the sentence.

According to an embodiment, the communication module 240 may connect the electronic apparatus 10 to an external device, for example, a server, another electronic apparatus, under the control of the processor 210. The communication module 240 may include one of the constituent elements implementing various wired or wireless communication methods such as wireless local area network (LAN), Bluetooth, and wired Ethernet, or the like, according to the performance and structure of the electronic apparatus 10.

FIG. 3 illustrates a state in which generality scores of character sets are used to identify one of a plurality of character sets on an electronic apparatus according to an embodiment.

According to an embodiment, the electronic apparatus 10 may calculate a generality score considering how frequently a character set including a word, a phrase, or a clause is used in a sentence, a paragraph, or a document, and store the generality scores in the memory 230 as a database. The generality score may be a score used to determine whether a character set in a sentence, a paragraph, or a document is highly likely to be selected by a user for search.

For example, the generality score may be determined considering at least one of the frequency of use of a character set, a degree of importance of a character set, and a possibility of an additional search using a character set. However, the factors to be considered in determining the generality score are not limited thereto.

The generality score may be determined, for example, according to whether a user is more likely to select a character set to get additional information because, although the character set is usually less frequently used in a sentence, a paragraph, or a document, when used in a sentence, a paragraph, or a document, the character set has an important meaning and thus is used as an important meaning in the sentence, the paragraph, or the document.

The generality score may be determined, for example, according to whether many people are likely to conduct a search for additional information regarding a character set because, although the character set is usually less frequently used in a sentence, a paragraph, or a document, when used in a sentence, a paragraph, or a document, many people are curious for the character set.

The generality score may be close to 1, for example, as the frequency is relatively high and a probability of searching for additional information is relatively low. Furthermore, the generality score may be close to 0 as the frequency is relatively low and a probability of searching for additional information is relatively high.

Referring to identification number 3-a of FIG. 3 , the electronic apparatus 10 may store a generality score with respect to a character set including a word, a phrase, or a clause. For example, the electronic apparatus 10 may give 0.73456 point to

, 0.52679 points to

, 0.41181 points to

, 0.01220 points to

on the basis of a plurality of sentences or documents collected as data and classified into a plurality of character sets.

Referring to identification number 3-b of FIG. 3 , the electronic apparatus 10 may identify

that is a sentence including

that is a character selected by a user. The electronic apparatus 10 may obtain a plurality of characters including

in the sentence, as one character set. Furthermore, the electronic apparatus 10 may obtain a character set adjacent to the character set including

in the sentence. For example, the electronic apparatus 10 may obtain

, and

as a candidate character set.

According to an embodiment, the electronic apparatus 10 may identify

as a character set having a low frequency and a high probability of searching for additional information on the basis of the generality score to the obtained plurality of candidate character sets.

The electronic apparatus 10, as illustrated in identification number 1-d of FIG. 1 b , may display the selected area notification object 120 on the display 11 to display the identified character set to be distinguished from other characters.

FIG. 4 illustrates a state in which an electronic apparatus according to an embodiment identifies a character set including a plurality of characters by using a grammatical structure of a sentence

According to an embodiment, the electronic apparatus 10 may classify sentence constituent elements of a sentence including a character selected by a user according to grammatical characteristics of the sentence constituent elements. The electronic apparatus 10 may store a sentence analysis algorithm on the memory 230, the sentence analysis algorithm being able to hierarchically classify sentence constituent elements, such as a word, a phrase, or a clause, included in one sentence by using, for example, a tree structure, to a level of a noun, a postpositional word, or a suffix.

The electronic apparatus 10 may hierarchically classify a word, a phrase, or a clause in a sentence by grammatically analyzing an identified sentence. For example, the electronic apparatus 10 may identify at least one of a noun phrase, a verb phrase, an adjective phrase, and an adverb phrase from the identified sentence. Furthermore, the electronic apparatus 10 may identify the part of speed of characters sets classified from the identified sentence. The part of speech identified by the electronic apparatus 10 may include, for example, a general noun, a suffix, and a postpositional word, but not limited thereto.

For example, the electronic apparatus 10 may identify

that is a sentence including

that is a character selected by a user. The electronic apparatus 10 may grammatically analyze the identified sentence.

For example, the electronic apparatus 10 may identify

as a first phrase in the sentence. Furthermore, the electronic apparatus 10 may identify

as a second phrase.

The electronic apparatus 10 may identify

in the first phrase

as a third phrase, and the part of speech of

as a first part of speech. The electronic apparatus 10 may identify

as a fourth phrase, and the part of speech of

as a second part of speech, the part of speech of

as a third part of speech, the part of speech of
